Research on Radar/AIS Combined Surveillance Technology

Aiming at the problems of low azimuth resolution, miss detection of close-range multi-targets and vulnerable to adverse sea conditions of airborne maritime surveillance radar, the radar/AIS combined surveillance technology is proposed. Through the target track fusion processing of airborne maritime surveillance radar and automatic identification system (AIS), the detection defects of air-based radar are compensated, and the surveillance system is more stable in adverse sea conditions, so as to achieve the complementary performance advantages between the two sensors. Simulation results show that the proposed technology not only helps to identify military or civilian targets, but also improves the target tracking accuracy and reliability of the surveillance system, which makes the proposed technology of great research significance.
